About the Role

We are looking for a Senior or Staff Security Engineer to join our security team and own our vulnerability management program, collaborate with several Engineering and Product teams as a Security advisor and support SecOps. You will operate with a high degree of autonomy — defining strategy, building processes, and acting as a trusted security advisor to our engineering organisation.

What You’ll Do

• Own the vulnerability management program end‑to‑end: strategy, tooling, prioritisation, and remediation tracking across dependencies, containers, and cloud environments.
• Define and maintain a dependency security strategy, including policies for third‑party library adoption and update cadence.
• Integrate and maintain security tooling in CI/CD pipelines (SAST, SCA, secrets detection, container scanning).
• Act as a security consultant to product and engineering squads — supporting design reviews, architecture decisions, and secure coding practices.
• Define and maintain security standards and guidelines practical for development teams.
• Manage and continuously improve the Security Champions program — growing security awareness and capability across engineering teams.
• Support SecOps in incident triage and response, contributing security engineering context where needed.

Requirements

• Strong knowledge of cloud security — IAM, network security, secure configuration best practices.
• Hands‑on experience with security tooling in CI/CD pipelines (SAST, SCA, secrets scanning, container scanning).
• Proven experience in a vulnerability management role, through the entire lifecycle.
• Passionate and knowledgeable about using LLMs for building robust security practices, including triage, secure code review, threat analysis and tooling.
• In‑depth knowledge of secure coding practices in Node.js, TypeScript, Python, and/or React.
• Familiarity with security frameworks and standards (e.g. OWASP, NIST, CIS Benchmarks).
• Strong communication skills, with the ability to translate risk for both technical and non‑technical audiences.

Nice to Have

• Experience with Semgrep for static analysis and custom rule authoring.
• Experience with Wiz for cloud security posture management.
• Experience running or contributing to a Security Champions program.
• Experience with threat modelling (e.g. STRIDE).
• Familiarity with SOC 2 and ISO 27001.
• Relevant certifications are considered a plus (e.g. CISSP, IaaS specific certifications).
